>I have no idea how to get the other ingredients for her,

One of them is hinted at by a somewhat nerdy person, and the
other can be hinted at in the library. Do some research like any
good student. *snort giggle*

>however I have lit the burner and put the coffee filter on
experiment #2.

That'll help, just not now.

>Nor do I have any idea about how I would go about getting the
shirt or money for the vending machine.

One is irrelevant, and the other you need to have a certain item
that you already have.

>I spoke to Gary in the library, then went 'back in time' for the
shirt (he told me he lost it 'last night' but couldn't find it 'this
morning'). No dice.

Yeah, it's dark there isn't it? Too bad you can't light it up
somehow. That would help a lot.

I can't figure out how to help the dude in the computer lab
either, although I have set the fire in the New Building and read
the counseler's file twice. I would really appreciate some help.
Here's my inventory

And that's the only thing I have left to do. So, I can't help you
there.
